NMDF212: Nutritional Biochemistry Case Study Assessment

Oral Presentation: Case Study Analysis

Task

In your clinical practice you may be part of an integrative medical team with cross-referral and shared case management of clients. Clear communication of the impact of dysfunctions in nutritional biochemical pathways on clinical presentations with both clients and colleagues is an important skill to develop in providing optimal client care. This task provides an opportunity to showcase your nutritional biochemical knowledge via case study analysis and evidence-based nutritional intervention strategies in a brief professional slide presentation to your colleagues.

Structure and Presentation

• Refer to the Assessment Specifications and marking rubrics for the Oral Presentation: Case Study Analysis located on LMS in the Assessments tab above this document.
• Watch the PubMed Clinical Trial Literature Search Video on LMS to support your research topic evidence search. Live Tutorial Workshops will also cover case analysis and nutritional intervention evidence search skills.

Case study

Carla is a 48-year-old female who has come to you for advice on nutritional medicine to support her overall health and well-being because she has been diagnosed with fatty liver (indicated by signs of elevated liver enzymes and cholesterol) and moderate depression. She complains of excessive fatigue, nausea, loss of appetite, disorientation, itchy skin, dark-coloured urine, muscular pain, and breathlessness (especially after climbing stairs).

Her biochemical assessment indicates iron deficiency, confirmed by the physical sign of spoon-shaped fingernails. There is also redness and swelling of the lining of the mouth, redness of the tongue, and angular cheilitis indicative of low B vitamin levels. Her skin is dry, and she often has dry eyes. She is always tired and stressed, and she complains of muscle weakness and memory loss which concerns her.

Carla recently accepted a new job and is finding it challenging and stressful. She mostly sits in her home office trying to complete all the allocated tasks but is proactive in spending some time in the sun during the weekends. She doesn’t have time or motivation to plan meals or cook and often buys takeaway or frozen meals. Carla is lactoovo vegetarian. When stressed, she drinks spirits with soda. She does not like fruit and has a shellfish allergy.

Assessment Summary

The Oral Presentation: Case Study Analysis is designed to assess your ability to:

• Integrate nutritional biochemistry knowledge into clinical practice.
• Communicate clearly with clients and colleagues about biochemical dysfunctions and their clinical implications.
• Develop evidence-based nutritional interventions tailored to a client’s specific health needs.

Key requirements include:

1. Case Analysis: Evaluate the client’s biochemical and clinical presentation.
2. Evidence-Based Intervention: Recommend nutritional strategies supported by scientific literature.
3. Slide Presentation: Deliver a concise professional presentation to colleagues highlighting findings and interventions.
4. Research Skills: Use PubMed and other clinical literature databases to support recommendations.
5. Professional Communication: Present findings clearly and succinctly, with logical flow and clinical relevance.

The case study focuses on Carla, a 48-year-old female presenting with fatty liver, moderate depression, iron deficiency, low B vitamins, and lifestyle-related challenges impacting her nutrition and overall health.

Mentor-Guided Approach

The Academic Mentor guided the student in a step-by-step process to structure the case analysis and presentation:

1. Initial Assessment & Biochemical Review:

   • The mentor instructed the student to first review Carla’s biochemical markers and physical signs (e.g., spoon-shaped nails, angular cheilitis, dry skin).
   • Emphasis was placed on linking these signs to nutrient deficiencies (iron, B vitamins, vitamin D).

2. Clinical Problem Identification:

   • The mentor guided the student to categorize health concerns into:
     • Liver function issues (fatty liver, elevated liver enzymes)
     • Nutritional deficiencies (iron, B vitamins)
     • Psychological and lifestyle factors (stress, depression, poor diet habits).

3. Research & Evidence Gathering:

   • The student was shown how to search PubMed for clinical trials and reviews on interventions for fatty liver, depression, and nutrient deficiencies.
   • The mentor emphasized selecting high-quality, peer-reviewed evidence and documenting sources for credibility.

4. Intervention Planning:

   • Using the evidence gathered, the mentor helped the student design nutritional strategies, including:
     • Iron and B-vitamin supplementation
     • Dietary adjustments within a lacto-ovo vegetarian framework
     • Lifestyle recommendations (stress management, sun exposure for vitamin D).
   • Consideration of allergies, preferences, and convenience (shellfish allergy, dislike of fruit, busy schedule).

5. Slide Development & Presentation Skills:

   • Mentor assisted in structuring slides to:
     • Present case summary
     • Highlight biochemical analysis
     • Outline intervention plan with supporting evidence
     • Ensure professional and clear visual communication (charts, graphs, and bullet points).
   • Focused on timing, clarity, and audience engagement during presentation.

Outcome & Learning Objectives Achieved

• Outcome:

  • A polished, evidence-based oral presentation addressing Carla’s nutritional needs.
  • Clear, professional slides linking biochemical assessment to practical interventions.
  • Confidence in communicating complex nutritional information to peers.
• Learning Objectives Covered:
  1. Apply nutritional biochemistry knowledge to clinical case analysis.
  2. Develop evidence-based intervention strategies.
  3. Communicate clinical findings effectively to colleagues and clients.
  4. Integrate lifestyle and dietary considerations into personalized nutrition plans.
  5. Use research skills to support recommendations and justify interventions.
